Wanting a blow off :)

[thewiizard]

Hey All,

I've landed myself a 1.8T and I'm wanting to get a 'dump valve' installed but the one I am interested in is not one where all the pressure is dropped straight into the atmosphere but the pressure is stuttered giving a chattering effect..

Any idea what type of vale this is?

Cheers,

Nick

Sounds like your talking about compressor surge to me!

wooshy wooshy wooshy.

Forge Split-R you want and please search.

 

[Ninja]

Yeah the forge split r will give the whooshing sound but not sure anything can simulate the chattering noise ? I thought that only happened when the turbo was knackering itself ?

 

[pj1985]

Uh Oh!!!

 

[si-mate]

Chatter on the 1.8t is bad. If you want chatter then buy an Impreza.

If you are want a reasonable "whoosh" then an open cone air filter and 007P will do the trick.

or just put the dv on wrong and ul have all the chatter u can imagine lol

 

[DaNnY_LaD]

my 007p is backwards and its loud no chatter

i think i know the sort of dv he is on about.
there is a couple of skylines round here running them.
I think the best thing to explain how they sound is that when the car is dumping, it sound like a air pipe is loose and is whipping around on the dump.

does that make sense.This thread earlier has one i think if you listen carefully (might be wrong)

I think there are a few people with skylines that don’t run a dv at all! What you can hear is excess “boost pressure” forcing itself back through the turbo (compressor surge, I think that’s what it’s called) creating the so called “chatter”! It’s been said to greatly reduce turbo life!

 

[cupra_brown]

there is a punto gt running one down here also.

If it is the case that they are reducing the turbo life....i wonder if they know

Well I don’t really know, I’m only reproducing things I’ve read on here. The sound can also be the product of a Defective dv.

 

[thewiizard]

its nothing defective however I do believe it something to do with the actuator diverting the air through the exhaust. A mates RS Turbo does it. Sounds lush.

chattering = stalled turbo

chattering = stalled turbo

Thanks for conformation!

its waste gate chatter i think ure after its done by a bung isnt it i was after the same sound but i was told by a tuner that it would mess everything sumet to do with the car thinking it wasnt getting rid of air inuf or sumet n it would send the car onto limp mode hope it helps abit

[caveo]

Boom!!!!

 

[Wastegate86]

its a wastegate surely?
use to have it on my old glanza
was achieved from an hks BOV and a ported internal wastegate on the turbo
